Front Lower wishbone bolt size?

[Bartman]

Hi all,

I need to replace the lower wishbone front bolts on my S2 imperial. Does anyone know the size of the bolt (maybe  1/2" x 3 1/2 ) but I am not near the car and want to order them up? 

 

Thanks!

 

Bart.

@Bartman - mine is a very early Cat imperial chassis from the late 70s so similar to s2 in many ways, from my observations . That said, my front lower wishbone uses a 1/2”-20x 3.5” long bolt (nylock nut)in the rear and a 5/16x1” bolt in the front (use spring washer and plan washer here)

 

hope that helps.

Thanks, managed to check it over the weekend, mine is 1/2 x 3 1/2 x 20. I am planning to drill and tap the bolt to take a 1/4 x28 stud which I can then use as part of a mount for a front wing.
